When building RefPositions in the TreeNodeInfoInit methods, it is very complex and messy to have the setting of the (debug-only) `minRegCandidateCount` spread all over. Instead, set them for all the RefPositions for a given node after they have been created.
This required the ability to create an iterator marking the end of the list, prior to creating the new ones.
In the process, eliminated the use of auto from lsra.cpp in the interest of strong typing, as well as avoiding the confusion of having things with `RefPosition` in their name that are actually iterators.
These changes originally caused failures with JitStressRegs because `getKillSetForNode()` had side effects - generating Kill `RefPosition`s for `MOD` & `DIV`. This is not actually necessary, and causes problems when the debug-only stress code was calling it *after* all the `RefPosition`s had been created. Also, this had the weird (existing) effect that duplicate kill `RefPosition`s were being generated in the stress case!

`remove` uses `erase` to delete the entry in list.
Since `erase` returns the next iterator, the iterator shouldn't be increased
when the entry is found and deleted.

This change is the result of running clang-tidy and clang-format on jit
sources.

RefPosition() builds a temporary object and initializes it with memset. push_back copies the temporary object to the list node. memset is called again to zero out the newly created RefPosition object.
Add emplace methods to jitstd::list to avoid copying. Drop the redundant memset call.

This removes the only usage of ArrayList in the JIT.

This change fixes some of the warnings in the jitter code on Linux. With this change
combined with an upcoming change in the rest of the codebase, 16 warning disabling
options can be removed.
The issues in the jitter were:
1) Incorrect typedefs for const_reference and const_pointer (the const was ignored)
2) Member initiazalization order in class constructor didn't correspond to the member order in some classes
3) Objects with vtables were copied via memcpy. While this is intentional, cast of the pointers to void*
is required to silence clang warning
4) Comparing values of different enums - there are cases of two enums containing the same values.
5) Casting int to pointer - the cast was legal (forming a handle), adding cast to size_t in between used to fix the warning
6) "static struct" - removed the static keyword
7) Missing return value in methods with _ASSERTE
8) Class name classifier on methods in the .h
9) Specialized template member functions need to be defined out of the class
